The multi-stream version of xfsdump for IRIX used sprocs for
threading. When a "thread" exits with sprocs, a SIGCHLD is sent to
the main thread just as if a regular child process exited. A future
multi-stream version of xfsdump would use pthreads, so the SIGCHLD
code is no longer needed. So:

- No longer register for or handle SIGCHLD (SIGCLD).
- Remove signal handling code for child processes.
- Remove cldmgr_killall() as there are no children.

Looks good,

does this mean you're actively working on multi-threaded dump for Linux?

Indeed...I didn't want to come right out and say it, in case I get side
tracked. :) But hoping to have patches up for review in the next week or
